Well, brass is a metal anyway, it can also be hardened (but not after machining) making very good tools. Also, don't count on what you see shining on Chinese products pictures is steel, because they specialize in mystery metal which is given a good look by plating, etc. If the seller is a specialized one or claiming to be "factory official" there is some chance that asking gets you a sensed replay, but if it's a dropshipper they will always answer what you want to hear.

There's an article in May's Horological Journal about both the Bergeon sets and the Chinese versions. Basically, both get criticised - the Chinese sets for having brass arbors made to look like steel and the Bergeon set for having duplicate arbors and too little variation in the width of the winders. 

Mark Lovick got a mention on the video he made testing the Chinese sets. 

They did highly rate Rolex winders but obviously they're well out of most amateurs' price range so June's edition has an article on how to improve the Bergeon set to be more like the Rolex winders... might be worth a try if you have a lathe and know how to use it?!

Take good measurements, add pictures, post all here and I'll see what I can do. 

Not my work, it's in the BHI's Horological Journal June 2021 an article by Justin Koullapis.  I can't scan copyright material then put it online, and I'm not sure I can translate the info into something usable either.

Never mind. Although I like to make parts on the lathe it's not like replacing a working brass arbor is a pressing matter, I think.

The June article is about upgrading the Bergeon winders to work like the Rolex winders, not to fix the Chinese ones. IMG_20210706_205713.thumb.jpg.8326274089323a7d386b6d77c81d0ccf.jpg

      What are these Seitz B-Jewels?

      By VWatchie · Posted

      I bought this box of jewels a few years ago and noticed that the glass containers are divided into two sections. In the first section, the containers have a label with red text colour and always start with the letter B. In the second section, the text on the label is black and lacks the letter B. There seem to be roughly the same number of containers in both sections, and each section has the same sizes of jewels. The only difference is that the jewels in the B section with red text have a slightly rounded, convex underside. My question is what are these rounded jewels for and if I can use them instead of the jewels with a flat bottom if a certain size is missing?

      Yes, as watch repairers we never ever use force, we use percussive persuasion! 🤣

      Trying to close the mainspring barrel pivot, but the hole simply will not close up

      By VWatchie · Posted

      I have a barrel bridge arbor bearing that needs a slight reduction. I have never closed a barrel bridge arbor hole before and my staking set has a very limited number of doomed punches and most of them are too small (go through the hole) or too short to fit in the lower section of my inverto-style Boley & Leinen staking tool. So, I'm considering ordering a few doomed punches from CousinsUK. My question is what sizes I should order? Is there a rule of thumb relating to the hole diameter? I too worried that reducing the hole size would increase the end-shake. Especially as Kalle Slaap talks about end-shake at the end of the video at 7:43, but then he just glosses over it by saying "You can just gently push the material back in", which I don't get at all 🤔 Anyway, I feel a lot less worried now after having seen @mikepilk's excellent illustration. Thanks!

      If you have access to a 3D printer, here is my design I did a few weeks ago:

      DIY Screw polisher

      By mikepilk · Posted

      I finished my polisher yesterday, and just tried it out. I'm surprised how easy it is to get a good result - just a couple of minutes. I thought it was going to be more difficult - a nice surprise as most things in watchmaking are harder than you expect. I bought self adhesive 3M lapping film https://www.cousinsuk.com/product/film-lapping-3m-261x266x , 9, 3 and 1 micron, and stuck it to sheets of glass. The 9 micron is course enough to remove large scratches.  I'm glad I used the M6 thumb screws as the large heads allow for small adjustments.
